    Back in Belgium, the scientists looked at the ants under an electronic microscope and found that their【C6】________, triangular hair reflects light like a prism (棱镜), giving them a metallic reflection and protecting them from the sun’s awful heat.

选项
答案 N
解析 形容词辨析题。空格位于不定冠词a之后，名词knife之前，因此空格处需要填入形容词。空格所在部分的句意为：当博士生昆汀.维洛特用一把_______刀从一只蚂蚁身上清除毛发。因为蚂蚁身体很小，所以用的刀子应该也是很小的，因此空格处应填入含有“小的”意义的形容词，故本题答案为N)tiny。
